Anaphase chromosome motion involves the disassembly of kinetochore microtubules. We wished to determine the site of kinetochore microtubule disassembly during anaphase in crane-fly spermatocytes. In crane-fly spermatocyte spindles, monoclonal antibody 6-11B-1 to acetylated alpha-tubulin labels kinetochore microtubules almost exclusively, with an area immediately adjacent to the kinetochore bein...
The generation of cortical projection neurons relies on the coordination of radial migration with branching. Here, we report that the multisubunit histone acetyltransferase Elongator complex, which contributes to transcript elongation, also regulates the maturation of projection neurons. Indeed, silencing of its scaffold (Elp1) or catalytic subunit (Elp3) cell-autonomously delays the migration ...
this research was conducted to investigate the effect of acetylation on weathering resistance of solid wood and particleboard produced from acetylated particles of fagus orientalis. after 12 hours soaking in acetic unhydride, in order to achieve three levels of weight gain, 5, 9 and 16%, acetylated particles of bech wood were heated in oven at 120oc for 30, 90 and 240 minutes, respectively. als...
Streptococcus pneumoniae is responsible for high rates of pneumococcal bacteremia, meningitis, pneumonia, and acute otitis media worldwide. Protection from disease is conferred by antibodies specific for the polysaccharide (Ps) capsule of the bacteria. Of the four types of group 9 pneumococci, types 9N and 9V cause the most disease, and both types are included in the polyvalent pneumococcal vac...
The colR4 and colR15 beta 2-tubulin missense mutations for lysine-350 in Chlamydomonas reinhardtii (Lee and Huang, 1990) were originally isolated by selection for resistance to the growth inhibitory effects of colchicine. The colR4 and colR15 mutants have been found to be cross resistant to vinblastine and several classes of antimitotic herbicides, including the dinitroanilines (oryzalin, trifl...
Inmunofluorescence staining of murine NIH3T3 fibroblasts grown at high density shows that conventional nucleoside diphosphate (NDP) kinases A and B localize to a sensory organelle, the primary cilium. Similar results are obtained with Xenopus A6 kidney epithelial cells, suggesting that NDP kinases are a universal component of the primary cilium. The translocation of NDP kinase into primary cili...
Human kinetochores are transcriptionally active, producing very low levels of transcripts of the underlying alpha-satellite DNA. However, it is not known whether kinetochores can tolerate acetylated chromatin and the levels of transcription that are characteristic of housekeeping genes, or whether kinetochore-associated 'centrochromatin', despite being transcribed at a low level, is essentially...
